PLEASE HELP ASAP ITS DUE REALLY SOON Use the periodic table to answer the following questions.

The radioactive atom 241/95 Am decays by alpha particle emission. Write a reaction showing the decay

Use the nuclear decay reaction to answer the following questions

. Does 239/94Pu undergo transmutation? Explain your answer

What is the binding energy of 1 mole of 238/94Pu if the mass defect is 0.001896 kg/mol

If you could even just answer 1, anything helps. Thanks!

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."

the solar system used to have much dust particles option no d

the volume increases

the correct answer would be d. hope this !
